In this video, Eric Roberts explains why doing many HIIT‑style workouts can stall progress. He argues that frequent HIIT creates high physiological stress that the body struggles to recover from. Insufficient recovery leads to two main problems: (1) a lack of strength and muscle gains because adaptation occurs during recovery, not during the workout itself, and (2) increased hunger and cravings, which make dieting harder and impede fat loss. Roberts recommends cutting HIIT frequency (4‑7 days per week) and instead performing 3‑4 strength‑training sessions per week to improve recovery, promote muscle growth, and support fat‑loss goals.
